This invention relates to gas adsorption apparatus of the type in whichrelative movementV takes place between the adsorbent holder andthe fluidsupply pipes, which\ relative movement `permits the continuous operationof the apparatus.

It is an object of the invention to provide Fig. 2 is a diagrammatichorizontal-.sec,

tion thereof.

In thej drawings, l represents an annular body of adsorptlve materialsuch as, charcoal, surrounded by an annular casing 2 de-' fining gasspaces 2al and 2b on opposite sides ofthe Abody ,.1. Radial partitions 3divide both the body 1` and the casing into a relatively large`number ofsector-like parts.

The'body 1 is carried upon an annular base 4 on the opposite sides. ofwhich are disposed annular plates 4 and 4:" provided with relaannulartutes a single operative unit. Itis su tively narrow sector-likeopenings a. The

the openings a ai'ord the only communication with the interior of thecasing. The structure thus far described constied upon an annular casing5 which is divided into two sections by a concentric `partition 5a bod ft e casing 5 and lthe artition 5, on the one hand, and between t epartition 5 and the. outer Wall of the casin is closedA by annularplates 5 and 5 prov1ded with relatively large sector-like openings 5deining relatively narrow webs c. Y A ,The body '1 together with casing2 `and annular base plate 4 ismounted upon the casing 5 forrotation,while the latter is sta-V tionary. The annular plates 4 and 4" coop--erate with the annularplates 5 and5d to control the lliow of 'gas intoand out oi? the plates 4 and 4b form closures andv Portfdefining at itsupper end a supplort 5h for the, 1. The space between t e inner wall 2".They are in `ell'ect material into the corresponding sections of' thegas space 2b and then rdown through openings a and ,b into the space. onthe" other side of the partition 5a.

The char ed generated y .passing steam or the like through the inlets 7upwardly into the corresponding gas vspaces 2", then through thechargedadsorption material and the resulting mixture 'of gas passes outthrough the outlet 8. y

The gas remaining after the charge with raw gas may be passed throughsuitable conduits 12, Iindicated in Fig. 2, through sections of the hotadsorption material after it has passed out of the regeneration zone, tocool it down and the gas cooled b condenser action' may lbe passedthrong inlets -9 through other sections of the body of adsorptionmaterial to cool it still further down to condition the adsorptionmaterial oradsorption.l Openings 10 and l1 indicate outlets fromtherespective sections.

The conduits and`connections in the casing 5may be arranged in variousways to su1t, 4partlcularl condltlons The materlal feasections of thebody 1 are reture is the single slidln contact surface bei tween plates4a', '4b an 1'5", 5d. Provisions can be readily made for preventingleaks of gas fromthis sin le contact surface.

The operation o the` apparatus will be apparent froin Fig. 2. Assumingthe'adsorbent carrier to be rotating in a clockwise direction, the pathsof the various fluids 'are indicated by the arrows. Raw gas enteringthrough inlet 6 passes through the adsorbent adjacent the inlet and isstripped -of the material to be recovered. The strip d gas then flowsthrough conduit 12,.,an

passes through-the hot regenerated adsorbent in the sectors above theoutlet openings 10; As

-t-he carrier rotates the charged sectors pass from the adsorbing zoneadjacent inle't to the regenerating o r recovery zone adjacent theoutlet 8. At this zone, steam or tl-ielike enters through openingsthrough the adsorbent to remove lthe.ad' sorbed material. The resultinggasmifxj'ture passes out through @the outlet 8`to suitablerecoveryjapparatus. The sections are cooled by the stripped gas as theymove over the outlets 10, and are subjected to further cooling as theypass through the zone adjacent the inlets 9. goes through the cycle ofadsorption, regeneration -and cooling each time the carrier makes onerevolution.

In the foregoing we have desdribed what f we'consider as a preferredembodiment of the the invention. The arrangement described.v 1sparticularly advantageous 'inasmuch as the problem of supporting therevoluble part and the problem of providing a single sliding contacthave found a common solution. It is understood, however, that the mainproblem of provlding assingle sliding contact surface may be solvedinvarious other ways.

'The arrangement of conduits for' giving the as stream the desiredcourse through different sections of the adsorption material is a matterof course in the light of the aforementioned application and does notforma' part of the invention proper.
